Abstract
Description
Technical Field
[0001] The utility model relates to the field of drainage of water receivers of building water supply and drainage facilities, in particular to a collecting type anti-blocking and capacity-expanding water discharger. Background Art
[0002] The drain is the beginning of the water receiver inside the building. As the first device related to the drainage process in the entire building, it should correspond to its function as much as possible. For example, the sink installed in the kitchen should avoid discharging too much washing residue (vegetable leaves and melon and fruit peels), and the sink installed in the bathroom should avoid discharging too much cleaning residue (hair and flocculent residue). Avoiding the discharge of residue into the sewer system is to make the drainage system in the entire building work smoothly and form good sewer water conditions.
[0003] Taking the kitchen as an example, the interception device of the traditional drain is a cylindrical shape with an unsealed upper end made of stainless steel. There are several small holes on the side wall and bottom of the cylinder, which serve as a collection and filtering device. When washing, the residue will gather inward. When the amount of collected residue is greater than the volume of the cylindrical collector, the filter hole is covered by the residue, which blocks the water from the receiver. This problem is very obvious in places with public washbasins. Taking the Twelve Residences of Ren'ai College as an example, when students wash dishes and clothes or wash their hands on a daily basis, the residue will be discharged into the sewer system, causing blockage, making the washbasin unable to be used normally. The dormitory aunt and the logistics teacher have also taken countermeasures - placing a circular filter at the drain outlet, reserving a circular drainage hole in the middle, and small holes in the rest of the parts. This measure can drain water faster when there is no residue. When intercepting water with residue, although it plays a filtering role, when the residue covers the holes, it will cause water to accumulate in the washbasin and cannot be discharged. For this reason, we proposed a collection-type anti-blocking and expansion drain. Utility Model Content

[0013] Preferably, the spring system comprises a spring, a baffle is fixedly installed inside the groove, and the spring is arranged on the baffle.
[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a collecting type anti-blocking and capacity-expanding drain, which has the following beneficial effects:
[0016] 1. In the collection-type anti-blocking expansion drain, the water containing residues is collected from the washbasin to the collection-type anti-blocking expansion drain. The water containing residues first passes through the filter cover, and the residues greater than or equal to the reserved filter cover spacing are first intercepted. This part of the residues is a small part and is deposited at the bottom of the washbasin pool. Then the water containing fine residues follows the water flow and the umbrella-shaped diverter to the bottom-opening drain below. At this time, the bottom-opening drain and the bottom-sealed expansion drain work together to collect residues and drain water. When the weight of the residues collected and the water not discharged in the bottom-opening drain and the bottom-sealed expansion drain is less than the tension generated when a single spring in the spring system deforms by 3 mm, the deformation of the spring system is small and can be approximately ignored. The spring system is stationary relative to the bottom-opening drain and the bottom-sealed expansion drain. When the weight of the collected debris and undischarged water in the bottom-opening drainer and the bottom-sealed expansion drainer is greater than the tension generated when a single spring in the spring system deforms by 3mm, the spring system will deform visibly, and the spring system will start to work. The bottom-sealed expansion drainer connected to the lower end of the spring system will move downward relative to the bottom-opening drainer, increasing the collection volume. When the weight of the collected debris and undischarged water in the bottom-opening drainer and the bottom-sealed expansion drainer is greater than the tension generated when a single spring in the spring system deforms by 90mm, in order to prevent the spring system from being pulled and the structure of the collection-type anti-blocking expansion drainer from being damaged, the safety device will start to work. At this time, the safety device installed in the groove on the outside of the bottom-opening drainer will forcibly prevent the spring system from continuing to deform, so that the bottom-sealed expansion drainer remains relatively still, and the entire drainer remains structurally intact without damage.
[0017] 2. For this collection-type anti-blocking expansion drainer, when the collected residue accounts for 95% of the collection volume of the drainer when it is fully working, the drainer working system no longer has a collection function, but only a drainage function. The residue in the collection container is mixed with water, causing the residue volume to expand. At this time, the height of the collected residue is flush with the bottom of the washbasin. The bottom-opening drainer and the bottom-sealed expansion drainer reach a full flow state, which reduces the flow rate of the surrounding water flow at the connection between the washbasin and the drainer. At this time, the washing water on the upper side of the sunken residue in the washbasin will continue to drain along the umbrella-shaped diverter through the filter screen on the filter cover, and flow to the central rapid drainer through the filter holes in the lower part of the umbrella-shaped diverter, and then quickly drain into the sewer through the fence net of the inverted truncated table of the central rapid drainer. At this time, because a small amount of air is gathered in the upper part of the umbrella-shaped diverter, the drainer will not have negative pressure to cause the residue to be siphoned into the sewer pipe, providing good drainage water conditions for the drainer. The residue intercepted on the outside of the filter cover will not be lifted up by the turbulent water flow. The utility model realizes the reasonable use of the sedimentation characteristics of the residue, reduces the possible blockage of the sewer, and solves the problem of unsmooth drainage caused by untimely cleaning of the drain to a certain extent.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 A collecting type anti-blocking and expandable drainer comprises a filter cover 1, an umbrella-shaped diverter 2 is connected below the filter cover 1, a central quick drainer 3 is fixedly installed below the umbrella-shaped diverter 2, a bottom-opening type drainer 4 is fixedly connected to the lower part of the central quick drainer 3, two groups of grooves with semicircular cross-sections are opened on the outer side of the bottom-opening type drainer 4, a safety device 6 is arranged at the outer groove, a spring system 5 is connected to the top of the outer groove of the bottom-opening type drainer 4, and a bottom-sealed expandable drainer 7 is connected to the lower end of the spring system 5.
[0026] Furthermore, both the bottom-opening drainer 4 and the bottom-sealed expandable drainer 7 have circular filter holes, and the bottom-sealed expandable drainer 7 is outside the bottom-opening drainer 4 .
[0027] Furthermore, the safety device 6 is located at one-third of the bottom-opening drainer 4. The safety device 6 consists of a hollow semicircular block and an isosceles triangle inscribed inside by two isolation plates. The circumference of the semicircle of the safety device 6 is equal to the circumference of the groove on the outer side of the bottom-opening drainer 4.
[0028] Furthermore, the central rapid drainer 3 is in the shape of an inverted truncated cone, the upper end of the central rapid drainer 3 corresponds to the lower end of the umbrella-shaped diverter 2, the upper part of the central rapid drainer 3 is composed of fences with a spacing of ten millimeters, and the lower part is composed of fences with a spacing of six millimeters.
[0029] Furthermore, the umbrella-shaped diverter 2 is conical, the upper part of the umbrella-shaped diverter 2 is composed of a cone, and the lower part is evenly covered by circular holes with a diameter of two millimeters, and the distance between each circular hole is three millimeters.
[0030] Furthermore, the filter cover 1 is hemispherical, the upper part of the filter cover 1 is composed of filter meshes with a spacing of 18 mm, and the lower part is composed of filter meshes with a spacing of 10 mm, and the diameter of the lower circular surface is equal to the inner diameter of the bottom opening drainer 4.
[0031] Furthermore, the spring system 5 includes a spring, a baffle is fixedly installed inside the groove, the spring is arranged on the baffle, a transverse cylindrical fixing part is fixed to the lower end of the spring, and the fixing part transversely passes through the bottom sealed expansion drainer 7 to connect the spring and the bottom sealed expansion drainer 7.
[0032] Working principle: When the water containing residue is discharged, the water containing residue is first filtered by the filter cover 1. At this time, the residue larger than the filter mesh spacing of the filter cover 1 and the oversized residue are first intercepted, and the remaining residue and water gather to the umbrella-shaped diverter 2. The umbrella-shaped diverter 2 drains the water containing residue to the bottom opening type drainer 4. At this time, the bottom opening type drainer 4 and the bottom sealing type expansion type drainer 7 participate in the collection and filtration work at the same time. When the amount of residue continues to increase, the spring system 5 starts to work, the spring system 5 stretches, and the bottom sealing type expansion type drainer 7 connected at the lower end moves downward relative to the bottom opening type drainer 4, so that the collected volume increases. When the weight of the collected residue and the weight of the water that has not been discharged reaches the limit of the preset spring system 5, the bottom sealing type expansion type drainer 7 will drop to the safety device 6 at the outer groove of the bottom opening type drainer 4. At this time, the collection volume reaches the maximum, and the drainer quits the collection work and has only the drainage function. When the amount of collected residue reaches 95% of the maximum collection volume (the residue is mixed with wastewater, causing the residue volume to expand), the lower part of the umbrella-shaped diverter 2 just contacts the upper interface of the collected residue, and a water seal that can slightly contain a small amount of residue is formed on the outer side of the lower part of the umbrella-shaped diverter 2, and a water seal containing only wastewater is formed on the inner side of the lower part. The inner side of the upper part of the umbrella-shaped diverter 2 contains a small amount of air to ensure that no negative pressure is generated during drainage, so that when the entire drainer reaches full load operation, a stable flow rate and flow state are generated. The water flow rate near the filter cover 1 will not cause the residue that has settled in the washbasin to be lifted up due to the high flow rate. The interception height of the lower part of the filter cover 1 is greater than the accumulated height of the residue accidentally dropped into the washbasin within 6 hours, and the water to be discharged will be quickly discharged in an orderly manner from the gap between the filter cover 1 and the umbrella-shaped diverter 2, the gap between the umbrella-shaped diverter 2 and the central quick drainer 3, the filter holes of the bottom opening drainer 4 and the bottom sealed expansion drainer 7, thereby truly achieving no blockage of the drain and reducing the amount of non-essential residue discharged into the drainage system.
